intriguing idea $30 or $40 annual membership and $2 service charge each time you recharge your account with a CC.
Warning Math below:
Presuming a 50¢ rise in fuel prices at 17MPG there is a 4¢/mile increase in fuel cost.
So at a minimum given this fuel price rise you would need to have purchased fuel for and drive at least 750 miles to offset the membership cost (which @ 4.75 a gal is $209). So you need to buy at least the 44 gallons to break even, so at least 2 tank fulls before you start to save any money.
So If you purchased the fuel earlier this spring you'd be saving money however I for one and I figure most of us here do not have the free cash lying around to "invest" in gas. Not to mention that they base it on RUG and if you "upgrade" to premium or diesel there is an "adjustment" made but no indication on what formula is used to make the adjustment.
Right now I don't see fuel prices rising too much more this summer and if prices go down you can pull your $$ back out but at the "lower of the market or purchase price"
